about "ao jewelry"

"ao" means blue in Japanese.
In Japan, there are more than 100 names for the color blue, and the color has been popular since ancient times as a color for expressing scenes and emotions. The name "ao" represents our wish that people can enjoy jewelry with rich expressive power like the color blue.
With the designs, which are born from the Japanese appreciation and love of nature, and the comfort of wearing them, the works are popular in fashion stores and famous department stores in Japan.
They have also gained a reputation for their safe metals made in Japan and careful craftsmanship.



Mayu Kobayashi

After graduating from Musashino Art University in 2004, she worked as a graphic designer, but had a strong desire to make things and taught herself to engrave. She established ao jewelry in 2015 and creates her works in Tokyo.
